Hi All,
I drive a 2011 Mazda6 2.5 L engine, error codes P0451 and P01450.
No smell of gas fumes
No emission testing in this area. Care runs perfectly fine.
When codes are erased they come back with time.
If it's cool and damp they come sooner.
If it's warm, hot and sunny the codes don't come on.
Should I worry about it?

P01450 is not a trouble code. there should 4 numbers.
Hey, if it runs okay I wouldn't worry about it. Especially if it only happens when it's damp, I could have some kind of a minor connector failure. You might just disconnect the wiring to the sensors, clean it with spray electrical cleaner and put it back on a little corrosion will often do that

Should I worry about it?
it may not be a problem yet, but the EVAP system is connected to the engine. It can also affect fuel delivery, and refueling at the station. I would want it in good working order.
